[0001] TECHNICAL FIELD

[0002] The present application relates to the technical field of recuperation beds. BACKGROUND

[0003] With the intensification of global population aging trend, recuperation equipment, especially for the elderly, recuperation bed, in the field of medical health is increasingly prominent. The traditional recuperation bed often has the defects of single function, complex operation, insufficient safety, etc., which is difficult to meet the diversified nursing and life needs of the elderly. Especially in the aspect of assisting getting out of bed, the design of the traditional recuperation bed often seems to be inadequate.

[0004] The function of assisting getting out of bed is an indispensable part of the old recuperation bed. When assisting the elderly to get out of bed, the traditional recuperation bed often lacks effective power mechanism, which leads to the elderly to fall or be injured in the process of getting out of bed. This not only increases the safety hazard of the elderly, but also reduces their quality of life.

[0005] CONTENT OF THE UTILITY MODEL

[0006] In order to overcome at least one of the defects of the prior art described above, the present application provides a recuperation bed. The problem of assisting the elderly to get out of bed can be solved.

[0007] The technical scheme adopted by the present application to solve the problem is:

[0008] A recuperation bed, comprising: a head unit; a tail unit; a main body frame assembled between the head unit and the tail unit; a bed plate main body rotatably connected to the main body frame, the bed plate main body can rotate in the plane of the main body frame, the bed plate main body is spliced by a plurality of hinged plates, so that the bed plate main body can be switched between lying and sitting positions.

[0009] By adopting the above scheme, the bed plate main body can be gradually inclined, thereby helping the elderly to more smoothly transition from lying to sitting, and by rotating along the plane of the main body frame, the angle of the bed plate main body when getting out of bed is rotated, and finally assisting getting out of bed. This gradual inclination reduces the instability factor when the elderly suddenly get up, and reduces the risk of falling.

[0010] In some embodiments, the bed plate main body comprises a back plate, a seat plate, a leg plate and a foot plate which are hinged in sequence, wherein a rotating shaft mechanism is arranged below the seat plate, the rotating shaft mechanism is rotatably connected to the main body frame, one end of the rotating shaft mechanism is fixedly connected to the bed plate main body, and the other end of the rotating shaft mechanism and the main body frame are provided with a rotary drive for driving the bed plate main body to rotate.

[0011] By adopting the above scheme, the bed board can be flexibly adjusted in angle to meet the needs of the elderly in different states. The introduction of the rotary driving part enables the rotation of the bed board body to be realized through simple control instructions, without the need for manual operation of complex mechanical structures, simplifying the operation process and reducing the skill requirements for nursing personnel.

[0012] In some embodiments, a back driving part is provided between the back plate and the seat plate for driving the back plate to lift or lower; a leg driving part is provided between the seat plate and the leg plate for driving the leg plate to lift or lower.

[0013] By adopting the above scheme, the independent arrangement of the back driving part and the leg driving part enables the user to accurately adjust the angle of the back plate and the leg plate according to individual needs.

Especially when the elderly need to change from a lying position to a sitting position or get out of bed, the armrest units play a particularly important role.

[0018] In some embodiments, the head unit comprises: a headboard upper support, the main body frame is assembled on the headboard upper support, the headboard upper support is provided with a first slide rod in the height direction; a headboard lower support, the headboard lower support is provided with a second slide rod in the height direction, the first slide rod and the second slide rod are slidingly connected; and a head drive connected between the headboard upper support and the headboard lower support, used to drive the headboard upper support to ascend or descend relative to the headboard lower support.

[0019] By adopting the above scheme, the height of the headboard is freely adjusted, allowing the user to adjust the height of the headboard according to individual needs, sleeping habits or body comfort, thereby obtaining a more personalized sleep experience.

[0020] In some embodiments, the tail unit comprises: a tailboard upper support, the main body frame is assembled on the tailboard upper support, the tailboard upper support is provided with a third slide rod in the height direction; a tailboard lower support, the tailboard lower support is provided with a fourth slide rod in the height direction, the third slide rod and the fourth slide rod are slidingly connected; and a tail drive connected between the tailboard upper support and the tailboard lower support, used to drive the tailboard upper support to ascend or descend relative to the tailboard lower support.

[0021] By adopting the above scheme, the height of the main body frame is raised by synchronously adjusting the height of the headboard upper support and the tailboard upper support, i.e. adjusting the height of the overall bed, so that the height of the bed can be adjusted according to the height of different users or their own preferences, providing more thoughtful and personalized nursing services.

[0022] In some embodiments, the bed plate main body further comprises a tailboard, which is aligned with the faces where the backboard, seat board, leg board and foot board are located.

[0023] By adopting the above scheme, it is helpful to maintain the flatness of the bed surface. When each part is closely attached and in the same horizontal plane, the gap or depression caused by unevenness can be reduced, thereby providing a more stable and comfortable sleep environment for the user.

[0024] In some embodiments, the tailboard, backboard, seat board, leg board and foot board each comprise a frame and a mesh frame, and the frame is arranged along the edge of the mesh frame.

[0025] By adopting the above scheme, the setting of the frame provides stable support for the mesh frame, so that the entire bed plate body can remain stable when bearing the weight of the user and various use actions; the design of the mesh frame makes the bed plate body have certain elasticity and air permeability.
